Domain aliases allow you to point several domain names to the same website. This can be useful, for example, for branding purposes.

To set up a domain alias in Plesk:

Run the Add Domain Alias wizard in the Websites & Domains tab.

Specify the domain for which you are creating an alias (the primary domain) and the alias’s domain name, for example alias.tld, and set up the following:

Synchronization of DNS zone with the primary domain

If this option is enabled, the DNS zone of the domain alias will be in sync with the zone of the primary domain. Any changes made in the DNS zone of the primary domain will be automatically applied to the DNS zone of the alias. For example, if you create the CNAME record like blog.primary_domain.tld, the corresponding blog.alias.tld record will be added to the zone of the alias.

Note: If a domain alias’s DNS zone is synced with the primary domain, you cannot modify resource records in the alias's DNS zone.
